My fiance needs to get off of a lease with three other people?

These people attacked and threatedn you... YOU SHOULD have called the police yourself. You need to call the landlord and tell him you had already paid and are to be removed from the lease immediately as the people threatend you and demanded you move out. I know it is not fun to call police but at this point it is he said/ she said... whose to say you didn't leave without all of that happening.. When youare threatened you have to go and make a police report in order to be taken seriously Hopfully the landlord is not a jerk.
